invention, such as will enable others skilledin the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, ters of reference marked thereon, which form apart of this specification.

Our invention relates to improvements in lawn sprinklers, in which buttwo sprinkler arms are employed, the said arms being arranged adjacenteach other and parallel for a short distance, then curved away from eachother, and finally curved toward each other at their outer extremities,adapted to oscillate in unison and operate alternately instead ofsimultaneously. Adjustable fingers are mounted upon the stationary stemof the device which coperate with a valve member located in a casing,the latter having horizontally disposed sprinklin arms projectingtherefrom and being rigi ly connected with a sleeve rotatably mounted uon the said stationary stem, whereby w en water is introduced, the valveis reciprocated to direct the stream of one sprinkler arm then shut itoff from that arm` and direct the stream through the other sprinklerarm, thus rotating the said sleeve back and forth and producing anoscillating movement to the sprinkler arms and valve mechanism.

An important feature` of our invention lies in the fact that theadjustable fingers can be set so that the sprinkler arm and valvemechanism can oscillate in an arc of any redetermined length, said archaving a ra ius equal to the distance from the center of the stationarystem to the outer extremities of the sprinkler arms. It must, of course,be understood that the water can be discharged from the extremities ofthe sprinkler arms in a corresponding arc of and to the charac- 'on anenlarged scale.

both arms much greater radius, depending entirely upon the form ofdefiectors or nozzles employed.

Having briefly outlined our improved construction, we will proceed todescribe the same in detail, reference being made to the accompanyingdrawing, in which is illustrated an embodiment thereof.

In this drawing,-Figure 1 is a top plan view of the device, showing oneadjustment of the fingers and the sprinkling mechanism at its oppositeextremities of travel. Fig. 2 is a section taken on the line 2-2, Fig.1, looking in the direction of the arrow, but Fig. 3 is a section 2,looking in taken on the line 33, Fi

ig. 4 is an end the direction of the arrow. view of a nozzle anddei-lector, looking in the direction of arrow 4, Fig. 1, said nozzle anddeector being mounted upon the outer extremity of each sprinkler arm,the said deflector shown in full lines above the nozzle and in dottedlines below the same.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a supporting bracket comprising a plate 6and depending members 7 Formed integral with the plate 6 and projectingabove and below the same, is a hollow elbow 8, the said elbow beingcurved`laterally below the plate as shown at 9 and its outer extremitythreaded to receive a swivel nut 10, which in turn is connected with a.hose 11 for supplying water thereto. The portion 12 of the elbow abovethe late 6 is perpendicular and offset invwar ly a short distance abovesaid plate,

said offset part being exteriorly threaded to receive the lowerextremity of a stem 13, which extremity is interiorly threaded for thispurpose. The stem 13 is stationary and has an inwardly offset portion14, said offset portion having a passage 4 therethrough, which registerswith the opening through the hollow elbow 8. An interior shoulder 15 andan exterior shoulder 16 are formed by the offset portion 14. A washer 17is located between the interior shoulder 15 and the upper extremity ofthe elbow portion 12, whereb a water-tight joint 1s formed. Upon theexterior shoulder 16 and surrounding the offset portion 14 of the stem13, is

of the o set portion 24, whereby mounted a casing 18 adapted to rotatethereon. The central portion of the casing 18 is enlarged at 19 to forman annular chamber 20, which is in communication with the interior ofthe stem 13 by means of openings 21 formed in the offset portion 14 ofsaid stem.

Above and below the enlargement 19, the casing 18 is provided interiorlywith circumferential grooves 22 and 23, which are filled with suitablepacking material to form a Water tight joint between the casing and thestationary stem. The upper extremity of the stem 13 is formed solid andhas au in# wardly offset projection 24 forming a shoulder 25slightlyabove the upper extremity of the casing 18, whereby themanipulation of the thumb nut 29, hereinafter described, will notVhinder the casing 18 from rotating upon the stem. The exterior of theoset portion 24 is smooth for a short distance above the shoulder 25,and then exteriorlyl threaded for the rest of its distance. Surroundinga part of this smooth portion and adjacent the shoulder 25, is placed awasher 26. Mounted above the washer 26 are two fingers 27 and 28provided with perforations at their inner extremities and ada ted to fitloosely one above the other aroun' the remaining portion of the smoothsurface and a sli ht portion of the threaded surface they may be turnedto any desired position. The thumb nut 29 is screwed upon the threadedextremity of the stem 13, and is adapted to lock the fingers in thedesired position. The enlarged portion 19 of the casing 18 is providedwith an opening 30 whose wall is threaded to receive the inner extremity31 of a valve casing 32, said extremity being exteriorly threaded forthis purpose, and having a assage 33 therethrough, one extremity o whichopens into the chamber 20. The opposite extremity of the passage 32opens into a chamber 34 located in the valve casing 32. The chamber 34is in communication with a cylindrical chamber 35 located in the forwardportion of the valve casing 32, by means of openings 36 and 37, theopposite ends of the chamber 35 protruding beyond the end Walls of thechamber 34 as disclosed at 38 and 39, and having caps 40 and 41respectively applied thereto, the caps having perforations therein asshown at 42 and 43. A cylindrical valve member 44 provided with twopassages 64 and 65 is fitted in the chamber 35 and adapted toreciprocate therein, the said valve member being of suitable length forthis purpose. The valve casing 32 is provided with openings 47 and 48having forwardly projecting interiorly threaded collars 49 and 50respectively, surrounding the same.

The inner extremity of a hollow sprinkler arm 51 is threaded into thecollar 49 and the inner extremit of a second sprinkler arm 52 isthreadedy arms project horizontally therefrom and are approximatelyparallel to each other for a short distance, then curved away from eachother, and finally curved toward each other at their outer extremities,the said extremities having nozzles 53 applied thereto and each nozzleprovided with a perforation 54 eccentricall arranged in their outerextremities. eiectors 55 and 56 are adjustably mounted upon the arms 50and 51, respectivel in the rear of the nozzles by means of lips 57 bentaround said arms and the said defiectors extend forwardly beyond theouter extremities of the said nozzles and are bent as shown at 58 insuch a manner that when the deflectors are arranged under the nozzles,these bent extremities will extend above the perforations 54, thusdirecting the stream of water upwardly, While, when the said deflectorsare arranged above the nozzles, the bent extremities will terminateabove the said erforations and not obstruct the Water. rlghisconstruction is best illustrated in Fig. 4.

The central portion of the valve member 44 is provided with an upwardlyprojecting pin 59 extending through and above an elongated slot 60formed in the top of thevalve casing 32. This pin is adapted to beengaged by the outer extremities of the fingers 27 and 28, which arefashioned as shown at 61 for this purpose to reciprocate the valvemember 44 back and forth in the chamber 35, thereby moving the valvepassage 64 from alinement with the opening 37 and the hollow sprinklerarm 51, and moving the valve passage 65 into alinement with the opening36 and the hollow sprinkler arm 52, or vice versa, as disclosed in Fig.3.

The side of the casing 18 opposite the opening 30 is provided with aprojection 62 having a weight 63 mounted upon its outer extremity tocounterbalance the weight of the valve casing and sprinkler arms.

In view of the foregoing description, the operation of our improveddevice will be readily understood. If the fingers 27 and 28 are adjustedas disclosed in Fig. 1, the

.water will flow'from the hose 11 into the elbow 8 upward through thestationary stem 13 through the openings 21 in said stem, into thechamber 20 formed in the rotatable casing 18. From the chamber 20 thewater will How through the passage 33 of the valve casing into thechamber 34 through the opening 36, the valve passage 65, opening 48,through the sprinkler arm 52 and out of its nozzle 53, thereby causingthe casing 18 to rotate upon the stationary stem 13 and the sprinklerarms to move from the full line position in Fig. 1 through an arcdisclosed by the dotted lines in said figure, in the direction of thearrow A. When the into the collar 50. TheseY sprinkler arms and valvemechanism have reached the dotted line position in Fig. 1, the pin 59will strike the finger 27 and the valve member 44 will be moved from thedotted line position in Fig. 3 to the full line position in said figure,whereby the water will then flow froln the chamber 34 through theopening 37, the valve passage 64, the sprinkler arm 51 and out of itsnozzle 53, whereby the casing 18 is rotated in the reverse direction andthe sprinkler arm and valve mechanism travel back through the are justdescribed, the weight 63 at all times counterbalancing the device andpreventing the casing 18 from binding upon the stationary stem 13.
